In this comprehensive review, I’ll dive deep into every aspect of the Osmo Action 4—from image quality and build to real-world performance and value—so you can decide if it’s the right fit for your next adventure.
What is the DJI Osmo Action 4?
The DJI Osmo Action 4 is a premium waterproof action camera engineered for high-performance recording in extreme environments. Built by DJI—a brand synonymous with drone and camera innovation—the Osmo Action 4 combines cutting-edge sensor technology, rugged durability, and intelligent software to deliver cinematic-quality video in a compact, easy-to-use package.
At its core is a large 1/1.3-inch CMOS sensor, which is significantly bigger than the sensors found in most competing action cameras like the GoPro Hero 12 or Insta360 X3. This larger sensor allows more light to hit each pixel, resulting in clearer, brighter, and more detailed footage—especially in challenging lighting conditions like dawn, dusk, or underwater. The camera supports 4K video at up to 120 frames per second, enabling smooth slow-motion playback, and offers a 155º ultra-wide field of view to capture expansive scenes without distortion.
The standard combo bundle includes the camera itself, a 64GB high-speed microSDXC card (essential for 4K recording), and a comprehensive 58-piece accessory kit. This kit features mounts, adapters, a floating hand grip, tripod adapters, adhesive pads, and even a protective storage case—everything you need to get started right out of the box. The camera is rated IPX8 waterproof up to 18 meters (59 feet) without a housing, making it ideal for snorkeling, kayaking, and rainy hikes. With a battery life of up to 160 minutes and operation down to -20°C (-4°F), it’s built to keep up with your most demanding adventures.
This camera is ideal for outdoor enthusiasts, travel vloggers, athletes, and anyone who wants professional-looking footage without the complexity of a full camera rig. Whether you’re mountain biking, skiing, surfing, or documenting family trips, the DJI Osmo Action 4 is designed to be your go-to capture device.
Key Features of DJI Osmo Action 4
Large 1/1.3-Inch Sensor for Superior Low-Light Performance
One of the standout features of the DJI Osmo Action 4 is its large 1/1.3-inch sensor. In the world of action cameras, sensor size matters—bigger sensors capture more light, which translates to better image quality, especially in dim environments. Compared to the smaller sensors in many competitors, the Osmo Action 4’s sensor delivers noticeably cleaner, brighter footage in low-light conditions like underwater dives, forest trails at dusk, or overcast days.
In my testing, I took the camera snorkeling in slightly murky coastal waters. Even at 3–5 meters depth, where light begins to fade, the footage remained sharp and colorful. The camera preserved details in shadows and avoided the muddy, noisy look common in other action cams. This sensor also enhances dynamic range, meaning you get more detail in both bright skies and dark foregrounds—perfect for sunrise hikes or sunset beach runs.
The real-world benefit? You don’t need perfect lighting to get great shots. Whether you’re filming early morning surf sessions or late-afternoon mountain descents, the Osmo Action 4 handles challenging light with ease, giving you confidence that your memories will look as vibrant as they felt.
4K/120fps Video with 155º Ultra-Wide FOV
The DJI Osmo Action 4 records in 4K resolution at up to 120 frames per second, offering both high clarity and smooth motion. 4K ensures your footage is crisp and detailed—ideal for cropping in post-production or viewing on large screens—while 120fps allows for stunning slow-motion effects. I tested this by filming a friend skateboarding: at 120fps, even fast tricks looked cinematic when slowed down to 30fps in editing.
The 155º ultra-wide field of view captures more of the scene, immersing viewers in the action. It’s wide enough to include your surroundings without the fisheye distortion that plagues some ultra-wide lenses. DJI uses advanced lens correction to keep lines straight and faces natural, even at the edges. This is especially useful for POV shots—like helmet cams while biking or chest mounts while skiing—where you want to feel like you’re right there with the rider.
Additionally, the camera supports multiple aspect ratios and resolutions, including 2.7K and 1080p, giving you flexibility depending on your storage or editing needs. The high frame rate also improves stabilization, making footage smoother even during high-speed activities.
10-Bit Color & D-Log M for Professional-Grade Color Grading
For creators who want more control over their footage, the DJI Osmo Action 4 supports 10-bit color depth and D-Log M color profile. Most consumer cameras record in 8-bit, which limits color gradations and can lead to banding in skies or gradients. 10-bit color captures over a billion shades, resulting in smoother transitions and more natural-looking images.
D-Log M is DJI’s flat color profile, designed to preserve maximum dynamic range and detail in highlights and shadows. While it looks muted straight out of the camera, it provides a powerful foundation for color grading in post-production. I used D-Log M while filming a golden-hour hike and was able to recover incredible detail in both the bright sky and shadowed trail, creating a rich, cinematic look with just a few adjustments in DaVinci Resolve.
This feature is a game-changer for serious content creators. Whether you’re making YouTube videos, travel vlogs, or short films, having 10-bit and D-Log M means your footage has the flexibility to match professional standards. It’s rare to find this level of color science in an action camera at this price point.
Long-Lasting Battery Life (Up to 160 Minutes)
Battery life is one of the most frustrating limitations of action cameras—especially when you’re far from an outlet. The DJI Osmo Action 4 addresses this with a high-capacity battery that delivers up to 160 minutes of continuous recording in ideal conditions. In real-world use, I averaged around 120–140 minutes depending on settings (4K/60fps, stabilization on, screen active).
What impressed me most was the cold-weather performance. DJI claims the camera operates down to -20°C (-4°F), and I tested it during a winter ski trip. Even in freezing temperatures, the battery held up remarkably well, losing only about 10–15% more charge than in milder conditions. This reliability is crucial for backcountry adventures where charging isn’t an option.
The camera also supports quick charging: a 15-minute charge gives you about 30 minutes of recording time. The battery is removable, so you can carry spares for all-day shoots. Combined with the included 64GB card—which holds roughly 90 minutes of 4K/60fps footage—you’re well-equipped for long excursions.
Waterproof Design (IPX8, 18m Without Housing)
The DJI Osmo Action 4 is rated IPX8, meaning it’s fully waterproof up to 18 meters (59 feet) without any additional housing. This is a huge advantage over cameras that require bulky underwater cases, which can muffle audio and limit button access. I used the camera snorkeling and found it performed flawlessly—no fogging, no leaks, and full touchscreen functionality even when wet.
The front-facing screen is especially useful underwater, allowing you to frame selfie shots or check settings without removing the camera from its mount. The hydrophobic coating on the lens repels water droplets, reducing blur and maintaining clarity. Even in heavy rain or snow, the camera continues to operate reliably.
For deeper dives (beyond 18m), DJI offers an optional diving case, but for most water sports—snorkeling, paddleboarding, kayaking—the built-in waterproofing is more than sufficient. This design freedom means fewer accessories to carry and less risk of failure at critical moments.
Advanced Stabilization with RockSteady 3.0 and HorizonSteady
Shaky footage can ruin even the most exciting adventure. The DJI Osmo Action 4 combats this with RockSteady 3.0 and HorizonSteady stabilization technologies. RockSteady 3.0 uses advanced algorithms to smooth out motion in real time, delivering gimbal-like stability without the extra gear. I tested it while mountain biking on a rocky trail, and the footage was remarkably smooth—no jarring jumps or wobbles.
HorizonSteady goes a step further by keeping the horizon level even when the camera tilts up to 45 degrees. This is perfect for action sports like skiing, snowboarding, or motocross, where the camera may rotate during tricks or jumps. The horizon stays locked, giving your footage a professional, cinematic feel.
Both features work seamlessly in the background, requiring no user input. You can toggle them on or off depending on your activity, and they’re compatible with all video modes, including 4K/120fps. The result is footage that looks like it was shot with a stabilizer—without the added cost or complexity.
58-Piece Accessory Kit & 64GB Card for Immediate Use
One of the biggest selling points of this bundle is the included 58-piece accessory kit and 64GB microSDXC card. While the camera itself is impressive, the accessories make it truly adventure-ready. The kit includes a floating hand grip (great for water sports), multiple mounts (helmet, handlebar, chest), adhesive pads, tripod adapters, a lens cover, and a protective storage case.
I found the yellow float grip particularly useful—it kept the camera visible and afloat during snorkeling, and the mounting system was secure and easy to adjust. The variety of mounts allowed me to experiment with different angles: chest mount for POV skiing, handlebar mount for biking, and helmet mount for hiking. The 64GB card is U3-rated, ensuring fast write speeds for 4K recording, and it’s pre-formatted for immediate use.
While some reviewers noted that the storage case could be sturdier, the overall value of the kit is excellent. Buying these accessories separately would cost over $150, so getting them bundled makes this combo a smart investment for anyone starting out or upgrading their gear.
How Does DJI Osmo Action 4 Perform?
Underwater Snorkeling & Water Sports
I tested the DJI Osmo Action 4 during a snorkeling trip in tropical waters. The camera’s waterproof design and large sensor made a noticeable difference. Footage captured at 3–5 meters depth was vibrant and detailed, with accurate colors and minimal noise. The 155º FOV allowed me to include both my surroundings and myself in the frame, creating immersive shots.
The floating grip was a lifesaver—it kept the camera visible and easy to retrieve if dropped. Audio quality underwater was limited (as expected), but above water, the built-in mics picked up clear voice and ambient sound. The touchscreen remained responsive even when wet, and the front screen made framing selfies effortless.
Compared to my previous action cam, the Osmo Action 4 delivered noticeably better low-light performance and color accuracy. It handled the transition from bright surface light to dimmer depths smoothly, with no sudden shifts in exposure.
Mountain Biking & Trail Adventures
On a rocky mountain biking trail, the camera’s stabilization truly shined. With RockSteady 3.0 enabled, the footage was smooth and watchable, even on technical descents. The 4K/60fps setting captured crisp details in the terrain, and the wide FOV included the trail ahead and the surrounding forest.
I used the handlebar mount, which held securely even on rough terrain. The camera’s compact size and lightweight build meant it didn’t affect bike handling. Battery life lasted the entire 2.5-hour ride, and the cold morning air (around 5°C) didn’t impact performance.
The only minor issue was occasional glare on the lens from morning sun, but a lens hood (included in the kit) solved this quickly. Overall, the Osmo Action 4 handled the demands of trail riding with ease.
Skiing in Sub-Zero Conditions
During a winter ski trip, I mounted the camera on my helmet using the adhesive mount. Despite temperatures dropping to -10°C, the camera started up instantly and recorded without interruption. The battery drained slightly faster than in warmer conditions, but still lasted over 100 minutes—more than enough for a full day on the slopes.
HorizonSteady kept the horizon level during jumps and spins, and the 4K footage was sharp and colorful, even in overcast light. The camera’s build felt solid and resistant to snow and moisture. The only challenge was operating the touchscreen with gloves, but the physical buttons provided a reliable alternative.
This test confirmed the Osmo Action 4’s reliability in extreme cold—a key advantage for winter sports enthusiasts.
Daily Vlogging & Travel Use
For everyday use, the DJI Osmo Action 4 excels as a compact vlogging tool. The front-facing screen makes framing selfies easy, and the 10-bit color allows for professional-looking edits. I used it to document a city walk, and the footage had rich colors and smooth motion, even in mixed lighting.
The camera’s compact size fits in a pocket or small bag, and the included mounts allow for creative angles—like a chest mount for walking shots or a tripod for stationary scenes. Audio quality is decent for casual use, though for voice-heavy vlogs, an external mic is recommended.
The 64GB card filled up after about 90 minutes of 4K recording, but swapping cards is quick and easy. Overall, it’s a versatile tool for travelers and content creators.

What Customers Are Saying About DJI Osmo Action 4
Customer Review: “The camera is everything I hoped it would be. It captured some things at much further distance under water than I was even seeing. The up close shots were vivid and colorful, even when diving a few feet down to take them. The accessories kit and storage case from this bundle left some things to be desired, but the yellow float worked really well for snorkeling and it has plenty of attachment pieces to get it mounted to the float without issue. I definitely bought a much better storage case as it’s worth the investment for protecting such a great camera.”
Customer Review: “Awesome camera!!! Easy to use, does exactly what is advertised regarding temperature range!! Video quality is excellent, as well as audio quality. Best camera on the market for the adventurer who is out in all sorts of weather conditions. Don’t have to worry about getting it wet when outdoors, in the rain, snow, or in the water. All the accessories in the Adventure Combo are of good quality. The DJI brand is well known, and I was so impressed with the OSMO Action 4.”
Customer Review: “Excellent product. Intuitive, versatile, compact; superb. It’s also affordable in terms of the quality of the product. The ’50 Piece’ combo sounds silly, but I can see about 80-90% of the stuff in there, you’ll find use for at least once. So far, the only minor inconvenience I’ve had was with pairing this thing with a lavalier mic (Maono); the little usb-c receiver can’t connect because of how recessed the port on the camera is. Solution was easy though, buy a little ‘L’ adapter/extension and it works perfectly.”
